Very light and variable winds at the field. We waited hoping that the wind will pick up and take on direction but it did not happen. It pretty much started to die off on us but even in these difficult conditions, both Rob and Pat were able to inflate and do a mockup takeoff. I normally do not allow students to do first solo in these kind of conditions but these guys made me think they can do it. Both Rob and Pat did their first solo in almost no wind conditions. Quite remarkable–both very well done.
